This issue only has to do with the Admin's Dashboard:
/wp-admin/
/wp-admin/index.php
/wp-admin/network/
/wp-admin/network/index.php

User's below Admin are not impacted. Other areas of the back end also do not appear to be impacted.

This is with CleanTalk activated:

I'm not sure how many customizing plugins CleanTalk is now conflicting with.

I figured it's better to let you know about this before I have to dig more about it, as you may be able to spot what you've changed in CleanTalk that would be doing this and that you could fix on your end without breaking CleanTalk's security features.

Using WP's troubleshooting on Anti-Spam by CleanTalk shows the right menu won't fly out when on the admin's dashboard. That's with no plugins network activated or primary-blog activated. The fly-out, however, does work on all other areas of the back end at that point.
